[jira] [Created] (ARROW-1854) [Python] Improve performance of serializing object dtype ndarrays
Wes McKinney created ARROW-1854:
---
Summary: [Python] Improve performance of serializing object dtype
ndarrays
Key: ARROW-1854
URL: https://issues.apache.org/jira/browse/ARROW-1854
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Wes McKinney
Fix For: 0.8.0
I haven't looked carefully at the hot path for this, but I would expect these
statements to have roughly the same performance (offloading the ndarray
serialization to pickle)
{code}
In [1]: import pickle
In [2]: import numpy as np
In [3]: import pyarrow as pa
a
In [4]: arr = np.array(['foo', 'bar', None] * 10, dtype=object)
In [5]: timeit serialized = pa.serialize(arr).to_buffer()
10 loops, best of 3: 27.1 ms per loop
In [6]: timeit pickled = pickle.dumps(arr)
100 loops, best of 3: 6.03 ms per loop
{code}
[~robertnishihara] [~pcmoritz] I encountered this while working on ARROW-1783,
but it can likely be resolved independently
